Redness Reduction & Soothing
Objectively quantify the anti-redness effect of your treatment through AI chromatic analysis, skin comfort measurement, and monitoring of skin reactivity.
The Client Problem
A dermocosmetic brand specializing in sensitive skin is developing a soothing anti-redness cream and must prove its effectiveness on diffuse redness and mild rosacea.
Redness is a common skin concern but difficult to assess objectively. Self-assessments are heavily biased by emotional state and lighting. The brand needs objective instrumental measurements to position itself against the segment leaders.
The identified challenges
- Objectively measure redness reduction (chromatic analysis)
- Assess the soothing effect and the reduction of skin reactivity
- Quantify perceived comfort and quality of life
- Demonstrate effectiveness under skin stress conditions (cold, UV)
Multi-criteria anti-redness evaluation
Sensitive & Reactive Skin Panel
Women aged 25-60 presenting diffuse redness or diagnosed mild rosacea.
Protocol with Skin Challenge
Measurement at baseline + after provocation (cold, capsaicin) to assess the protective effect.
Chromatic baseline
Standardized photos, AI mapping of the skin's a* (red axis)
Daily use (42 days)
Twice-daily application, weekly photos, comfort journal
Cold challenge
Controlled exposure to cold (5°C, 10 min): measurement of reactivity before/after treatment
Assessment & emotional experience
Final mapping of redness, comfort score, avatar interview on quality of life
Chromatic and sensory analysis
AI Chromatic Analysis
Pixel-by-pixel mapping of the a* axis (red-green) in Lab color space to objectively quantify redness.
Reactivity Test
Measurement of the vascular response after challenge (cold, capsaicin).
Comfort & Sensations
Comfort scales: tightness, tingling, warmth, dryness.
Quality of Life
Impact of redness on daily life via conversational avatar.
Conversational Avatar
AI-guided interview to collect declared perceptions.
